  spindle;
• a cell plate which forms centrally and progress centrifugally;
• primary plasmodesmata that provide intercellular links, structurally comparable to plant plasmodesmata;
• The flagellated cell of the charophytes is very similar to that found in the sperm of bryophytes and some vascular plants. Both possess an asymmetrical flagellar system of microtubules.
• the breakdown of the nuclear envelope at mitosis;
• presence of phytochrome, flavonoids and chemical precursors of cuticle.
